Quick-rev LS1 recipe?? I'm currently building a twin turbo 408, and I am trying to get it in and out of the RPMs real quick. Almost like a pro street kinda rev.
Does anyone have any thoughts on how to get a snappy LS1? Also, I am trying to avoid a HUGE cam, because it is going to be a daily driven turbo car.
4.030" Bore, 4.00" Stroke, TH400 auto (have yet to pick a stall).
Any thoughts on this would be great.
Thanks for your help.

LOL...
Kinda like this..except a lot tamer, because it's a street car. Haha
Now...I know this car has a HUGE cam.
Pro Street sound
This is a bit exagerrated compare to the sound I'm lookin' for.
I'm just trying to avoid how slow most LS1s come back down to idle after being revved. The quick drops in RPMs are the ultimate sound of power...I love it.

Now, you may be able to tune the PCM to give you what you want, I don't know.

Hmm...thanks for the info. I've never heard about that before. I am fairly new to the whole EFI/LS1 world. I usually play with carburated engines.
Hopefully someone will chime in with a possible solution.
Thanks again.

As for revving up fast, make more power 
But for the coming down, I'm with the IAC stepper idea. Decrease the use of the IAC or increase its closing speed. Or...carb the LS1?

Yeah, but have you guys checked on the prices of lightweight LS1 cranks, rods and pistons. That **** isnt cheap by any means. And he will likley end up with atleast 6k in the rotating assym by the time its ready to go into the block.
